Workers repair a broken water main pipe at NW 23rd Place, which closed the road between Burnside and Everett, Oct. 20, 2014 (KOIN 6 News)

PORTLAND, Ore. (KOIN 6) — A cast-iron water main pipe broke in Northwest Portland in the early hours of Monday, shutting one road and bringing emergency crews to the area.

The pipe at NW 23rd Place and Westover broke around 1:30 a.m. and flooded the street. The road is closed between Burnside and Everett and will likely be closed all day.

Several businesses in the vicinity are without water as well as a high-rise in the neighborhood, said a Portland Water Bureau spokesperson. Officials said water service is expected to be restored by 6 p.m. though the intersection will remain closed.

Crews are working with other utilities to determine where utility pipes are, she said. That way the water pipe can be removed and replaced.

This pipe is at least 50 years old and likely older, she said. Cast iron stopped being used in the 1960s.
